It appears that Apple has been right all along that Flash is not the future of the web. Unity this week announced that it will be phasing out support for Adobe Flash development.

Unity is a multi-platform game engine that is capable of producing games for consoles, PCs, touch devices, and the web. In particular, the engine has been used to create some of the most popular mobile games in recent years, such as Rovio’s Bad Piggies.

David Helgason, CEO of Unity, announced in a blog post on Tuesday that the company has stopped selling Flash development licenses.

Unity will continue to support its existing Flash customers “throughout the 4.x cycle.” Bug fixes will be made in future Unity 4.x iterations, but further development for the Unity engine on the platform has ceased.

The decision was made, Helgason stated, because of Adobe. Helgason called recent versions of Flash unstable and stated that, “We don’t see Adobe being firmly committed to the future development of Flash.” He also pointed out that Adobe has cancelled the Flash Player Next project.

Instead of Flash, Unity will be concentrating its development on its own Unity Web Player. Helgason stated that the Unity Web Player is installed on over 200 million computers and is used by one-third of all “Facebook gamers.”
